SPECIFICATION formingpart of Letters Patent No. 782,332, dated February 14, 1905.

Application filed April '7, 1904. Serial No. 201,996. A

To all whom, it may concern):

Be it known that we,iHUGo GoLDsMITH and EDGAR J. GOLDSMITH, citizens of the United States of America, and residents of the city of Cincinnati, 1in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Striking-Bags and Swivel and Universal -Joint Attachments Therefor, of whichthe following is a specification. y

The several' features of our invention and the various advantages resulting from their luse conjointly or otherwisewill be apparent from the following description and claims.

In the accompanying drawings, making part of this application, and in which similar letters of reference indicate corresponding parts, Figure l is an exterior viewof a striking-bag provided with our improved rotatable attachment and showing the preferred mode of adapting the bag to hold the rotatable attachment. The upper end portion of the bag is broken away to reveal the construction of the bag and of the rotatable attachment. Fig. 2 is a' vertical central'section of the rotatable attachment, on an enlarged scale, the connecting rope or cord lbeing shown in elevation. Fig. 3 represents an elevation of a punching or striking bag provided at each end with a rotatable attachment and adapted by our preferred mode to duly hold these attachments in position. The ropes respectively connected to the upper and lo'vilfer T iis figure is on substantially the'same scale as Fig. 1. Fig. 4 is a view in perspective illustrating the lower portion of the joint or'at-V tachment'adapted to be attached in amanner differing from that in which vwe have illustrated it as secured in the Figs. 1, 2, and 3.

Fig. 5 is a view of the joint when viewed from.

Figs. 1 and 3 are of one scale. FigyQ is on an enlarged scale. Figs. 4 and Bare on a common scale; but this scale is somewhat less than that of Fig. 2.

bell shape.

of it any suitable material may be employed.

The bag is preferably composed of sections A3. The latter are suitably united together, preferably by a row or rows of stitching at their inner side. This bag has the usual opening A3 for the reception of the bladder or inflatable bag H, the latter being of rubber or any other suitable material and of thev desired construction. Vhen the common form of bladder is employed, it will have a neck H2, whose end may be bent uponitself and tied fast with a cord H3. In this manner the air within the bladder when infiated will not be allowed to leal; out. At the end or top of the bag we locate our improved rotatable attachment.

The latter is substantially as follows: We provide a stiff framework B, preferably of a The end B2 toward the interior of the bag is open. The end B3 opposite to end B2 has an opening C centrally located relatively to the frame B and adapted to receivev the upper end portion of the frame D. Within the frame B and adjacentv to. the end B3 welocate a frame D, forY the most part spherical or approximately of that shape. This spherical` frame has an opening D2 large enough to freely receive the usual rope R or cord, whereby said bag is held to'that end of it. The frame B is adapted to receive the rounded frame D and allowthe latter to oscillate after the manner of a universal joint. This rounded frame D is-preferably a sphero-segment in eX-g ternal conformation and when made as preferred and yshown has a central opening and chamber. to receive the rope which is connected to .the striking-bag.- This frame D is suitably held to place in the frame B, preferably by a device we have invented, towit: a ringE, adapted to fit within the frame B and opposite the shoulder or annular fiat part B4 of the frame B. This ringE is properly con- 'cave atits inner side to embrace the adjacent p ortion of the sphericalframeD. yThus when the ring E is in placeitsecurely retains the frame D in position 'and'at the same time permits this frame to freely oscillate and the frame B to turn around it. The ring is removable to allow of the ready insertion of the frame D into place within the frame B. It is better to do this than to make the frame B in sections. We prefer to make the ring E adjustable to and from the part B4 of the frame. This we do by means of two or more screws E2 screwing into the frame, preferably at the part B. Byk duly operating the screws E2 the ring is advanced toward the part B* or retracted therefrom. We are thus enabled to hold the frame D in close proximity to the frame B and yet leave it loose enough within its holdings to allow it and the frame B to turn freely relatively to one another; but other modes of advancing and retracting the ring may be present. One of such means would be to form a screw-thread on the periphery of the ring and adapt this thread to engage a screw-thread on the interior of the frame B. When this rotatable device is duly connected to the bag A and the cord R having been inserted through the opening B3 and the opening O and knotted at RZ within the frame D, the device is in working order; but the knot may be omitted, and other means of fastening the cord R with the frame D may be present. When the bag is struck to one side of the center and in response to the blow rotates laterally, it can freely do 'so, and this without twisting the cord R. The frame B will whirl or revolve with the bag and around the frame D. The frame D and the cord will. not be turned. As before observed, the bag, if struck above or below the center, is free to oscillate relatively to the cord R, because the frame B can turn upon the frame D.

While the rotatable device can be connected to the bag outside of the latter, and in some instances it is desirable to do so, yet in many, if not most instances, it will be desirable to form a closer union to accomplish certain advantages we have in mind. To this end we extend the sections A2 of the bag and form an extension-chamber A5. lllithin this latter we locate the rotatable device. The sections of the material of which the bag is made curve up and lit closely around the outer part B of the rotatable attachment. Such isits shape and the form of the chamber A5 that after being located in the chamber it will retain its place there without any fastenings, the friction and pressure of the leather of the bag at chamber A5 being' sufficient to hold it in place.

When the bladder or inner inliatable bag H is filled with air, that end of the bladder adjacent to the rotatable device will'press against it and aid in 'securely holding' it to place when the bag A is spread out and might exert less friction on the sides of the frame B. The adjacent end of the bladder H is liable to press against the under part of the spherical part D. Thus it would obviously clog the conjoint operation of the parts D and B.

We prevent such interferences by means of a stili guard K, extending from the under part of the ring E to the opposite part of this ring E. lVhether this guard be in the form of a sheet, or of one or more ribs, or of a mesh of wires, &c., is not vital to the essence of the construction. This guard may be in one with the ring E or be separate therefrom, as shown. In the latter case this guard is preferably held by the screws E2.

.When the striking-bag is what is known as `a double-ended one, each end being adapted to carry its cord, the latter to be fastened to a suitable holding part or anchorage, we prefer to use our improved swivel device at each end and also to employ the special construction of the end of the leather bag as shown in Fig. 1 and as hereinbefore described. The bag will then exhibit the form and make shown in Fig. 3. In such event one of the cords R, or both, will usually be elastic for obvious reasons.

When desired, this rotatable joint device may be put on the outside of the bag, and in one mode of connecting the same to the bag the material of which the bag is made may be forced up inside of the frame B; but when preferred the end B2 may be closed and the connection be otherwise.

As hereinbefore suggested,- we expect that the joint device-may be used independently of the special form of bag we have shown. One form of the various means that may be employed forthe attachment of the rotatable attachment or device to the article with which it is to be used is indicated in Fig. 4, in providing the edge of the flange B5 with holes B6, wherein screws may be used. One of the varioususes of such construction may be for attaching the rotatable device to an overhead platform for supporting the rope of the striking-bag, &c.

What we claim as new and of our invention, and desire to secure by Letters Patent, is-

l. In a rotatable attachment, the combination of an outer frame, provided with a top opening, a convex receptacle Within having an opening in its top, for the reception ofthe cord, a piece adapted to embrace an under or rear portion of the convex receptacle, and means for enabling it to be secured in position to the outer frame, substantially as and for the purposes speciied.

2. In a rotatable attachment, the combination of an outer frame, provided with a top opening, and open at the bottom, a convex receptacle having' an opening in its top for the reception of the cord, an annular piece adapted to embrace an under or'rear portion of the convex receptacle, means for enabling it to be secured in position,and a guard located below and across the space in the outer frame and vbelow the convex receptacle, substantially as and for the purposes specified.

3. The combination of a rotatable attachment for the rope, and a striking-bag which is IOO at the end extended uponthe outer frame of the attachment, and covers and holds thelatter' in place, substantially as and for the purposes specified.

' 4. The combination of a rotatable attachment for the rope, and a striking-bag which is at the end extended over the frame of the attachment, the frame of' the latter provided with a lower outer annular'extenson, adapted lto t the-swell ofthe bag at the base of the IO said extension, substantially as and for the purposes specified.
